`Application `inea March 2a, i923, Semi no. 627,123, and maus/frana october 10,1922;

rl`lie object of this invention is to pro- Y vide a resilient ywheel in which the pneumatic tube is situated between the hub and the rim, thereby eliminating all risks of pu'nctures, suchas occur with the pneumatic tyre at present in use.` y Y It consists of a rim divided into two parts,

-tlie line of division .being centrally through tlievrim in the plane of rotation. This rim is provided with means for securing a solid rubber tyre around its periphery, the inner faces of the twoparts being provided with flanges that form a deep annular channel when thev two parts are in position.A A sheave like member also divided into two parts similarly to the rim and having a deep flange at each side forms the hub of the wheel, the annular channel formed byY these flanges'co-acting with the annular channel in the rim to form an approximately oval shaped chamber between .the rim and the hub. The base of each of the channels just referred to is corrugated the pneumatic tube that is housed within the chamber ,being Y provided with similarV corrugationsthat en-y gage withthe corrugations in the channels s o as tol prevent the tube or band creeping within the cliambei. n The lparts of the wheel are secured'together by means of discs that are bolted to each side of the rim the bolts being placed at intervals and passing throughthe ,discs and the two. parts ofthe rim. These discs kare provided with centrallyV situated circular openings. of a' larger diameter than the bore of the hub so thatthe motion of thewlieel relative lto the hub ymay Y v be eccentric.-v The opposing facesV ofvarious parts are provided with antifricti'on-ball bearings so arranged as to prevent thel opposing faces from actually?V touching one another. A. centrally situated circular flange upon the outer face of one 0f the discs on the outside of the wheel is provided with a screw cap to exclude dirt or moisture. y

A more detailed description will now be given and reference will be made to the accompanying drawings in which Fig. 1 is a side elevation of the wheel, portions of which have been broken away to show the relative position of the various Parts Figi 2 is a perspective view of certain of the parts vof the wheel placed in the tarder a when they assembled.

Fig. 3 is a central sectionalelevation of one-half of the wheel. I y l r1`he pneumatic tube 5 inthis wheel is placedbetween the rim 6'-61V and the hub l7;-71, the latter-'member being. slidably mounted between two discs 8,tl1at are secured, one on each sideV of the wheel, by means of bolts 8 that ypass ,through the two halves 6-.61 of the rim, so that.res iliencc is obtained by the compression of the pneumatic' tube between the hub and the rim. rllhe hub, 7 7a is divided into two halves, and rigidlysecured by countersunk screws 7, the heads of the screws being flush with Vthe inside face of one of the plates 10the The riin of the wheel is formed lintotwo halves 6 and '62 the divisional line 6" being in the plane of rotation. Upon the pe-V ripheral surface of each half ofthe rim is fa transversely concave annular recess 13 the outer ends of whichv merge `into. inwardlyturned ennular beads 14 by means of which Y the solid rubber tyre .15 issecured to the rim.- v 1 p Formed centrally upon the inner surface of the rim (3f-6a is an annular channel 161 each side of which'islextended radially'vinward to forni, flanges 17V upon the-outer surfaces of which the balls 12 lmay roll..

nular channel 9 together forni an Vapproximately oval shaped annular chamber that forms a housing fory the pneumatic tube 5.

VWhenl the Vparts are secured together the.- ychannel 16, flange 17, annulus l10a and an- The discs 8 are provided with annular i ribs 18 near their peripheiies, each `half of the riin 6--6a being provided with an annular rabbet 19 to form a bearing surface, for these ribs. `Between the annular rabrim has a second annular rabbet 20 which,

vwhen the parte are in position forms a recess i bets 19 and the flanges 17 each half of tlie' ,I l

the annulus n ofthe Vplate l0 to move Y radially inany direction. At intervals vthe outer faces of the plates 10 to accommodate-balls12t that form antifrictionv bearings between the outer faces of the plates and the inner faces of the' discs 8.

The `tube may lbe l'made of rubber or rubber Vand canvas and will be provided with a'ztlibe 26 rhaving an air 'valve 27 that lies" LIVin"the-passage. 28fcut through the disc 8,"y
